Iran war drives up costs for US banana producers

• The war in Iran has increased fuel and fertilizer costs for banana producers.
• Diesel prices have risen 70% since the war began.
• Banana fertilizer costs have also increased due to Middle Eastern natural gas prices.
• Some farmers have already switched to producing other fruits due to rising costs.
• Banana contract prices are set to expire in December.
• Past import tariffs on bananas from Central American countries have been lifted.

The war in Iran has created a cascade of economic effects impacting the global supply chain, including the production and pricing of bananas, America's most consumed fruit. Rising costs for essential inputs like diesel fuel and fertilizer are squeezing banana producers, who have historically operated on thin margins.

Diesel prices have surged by 70% since the conflict began in February, directly increasing the cost of refrigerated transportation. Additionally, the price of banana fertilizer, which relies on natural gas from the Middle East, has also shot up. These pressures, compounded by tariffs and a truck driver shortage, have created a challenging environment for the industry.

Industry leaders, including Danny Dumas, president of Del Monte North America, and Tom Stenzel, president of the Banana Association of North America, have described the situation as a crisis. One producer reported a 5% increase in costs compared to the previous year, with some farmers already seeking alternative crops. While current contract prices are locked in, there is uncertainty about whether grocers will pass on future price increases when contracts expire in December.

Historically, the banana supply chain has been optimized for efficiency and low cost, with a single banana costing around 15 cents. However, past price hikes in 2025, reaching 67 cents per pound, were attributed to import tariffs that have since been lifted. Despite these fluctuations, overall banana costs in August were 2.2 percentage points higher than the previous year. The industry also faces long-term threats from plant diseases like Panama disease, which has previously wiped out banana varietals and continues to threaten the dominant Cavendish variety.
